""" Create an empty class 'Empty'. """

""" Create a class 'Coordinate' which has two attributes 'x' and 'y' initially set to 0, and no constructor. """

""" Create a class 'Circle' with an attribute 'radius' that is set with a constructor. """

""" Create a class 'Rectangle' with two attributes 'width' and 'height' with a constructor that takes a width 
and optionally a height. If no height is provided assume it is a square and set height to width. """

""" Create a class 'Printer' which has a constructor that takes in a list of numbers. Make sure that when
calling print on the object we see the list of numbers separated with a semicolon. No semicolon at the end! 
e.g. print(Printer([1,2,3])) -> 1;2;3"""

""" Create a class TextAnalyzer whose constructor takes in a string. Create the following methods:
    - character_count: which returns the number of characters (excluding whitespace)
    - word_count: which returns the number of words. Hint: use split, and replace to turn punctuation to spaces.
    - sentence_count: which returns the number of sentences. Every sentence ends with an ending punctuation.
    - average_word_length: which returns the average word length.
    - average_sentence_length: which returns the average number of words per sentence.
    - compute_frequency: which will return a dictionary with each key being every unique word lowercased
        and value being the number of times that word (case-insensitive) appears in the text.
    - lexical diversity: which returns number of unique words over total words (keep as proportion).
    - fkgl: which returns (0.39 * average sentence length) + (11.8 * (average word length / 5)) - 15.59 """

""" Create three classes: Furniture, Chair, and Screw. Furniture has a single string attribute of 'material' with a suitable constructor.
Screws have a single string attribute 'head' with a suitable constructor. Chairs are Furnitures and have Screws with a suitable constructor. Create
methods 'get_material' and 'get_number_screws'. """

""" Create the following four classes: GameCharacter, Warrior, Archer, Mage. GameCharacter has a single method of attack. All 
other classes inherit from GameCharacter and override the attack with their own print statement. Warrior prints 'Warrior attacks with a sword!',
Archer prints 'Archer attacks with a bow!', and Mage prints 'Mage attacks with a staff!'. """
